What is PCR Testing?
PCR (Polymerase Chain Reaction) is a laboratory technique that amplifies small segments of DNA or RNA, making it possible to detect pathogens that would otherwise be invisible to traditional testing methods.
Think of it like a molecular photocopier: if a pathogen's genetic material is present in your sample—even just a few copies—PCR can make millions of copies, allowing our instruments to detect and identify exactly what's causing an infection.
This technology earned its inventor, Kary Mullis, the Nobel Prize in Chemistry and has since become the gold standard for diagnosing infectious diseases worldwide.

How PCR Testing Works
From sample collection to results, here's what happens when you order a PCR-based molecular test from Modern Diagnostics.
Sample Collection
A specimen (urine, swab, blood, etc.) is collected from the patient using our specialized collection kits designed to preserve DNA/RNA integrity.
DNA/RNA Extraction
Genetic material is carefully extracted from the specimen using automated systems that ensure consistency and prevent contamination.
Amplification
The PCR machine creates millions of copies of specific genetic sequences. If the target pathogen is present, even in tiny amounts, it will be detected.
Detection & Analysis
Fluorescent markers reveal which pathogens are present. Our advanced software analyzes the results and generates a comprehensive report.
Why PCR is the Gold Standard
PCR molecular testing offers significant advantages over traditional culture-based methods for diagnosing infectious diseases.
Unmatched Speed
Results in 24-48 hours vs. 3-7 days for traditional cultures. Faster diagnosis means faster treatment.
Superior Sensitivity
PCR can detect pathogens even when present in extremely low quantities—catching infections that cultures might miss.
High Specificity
Identifies the exact pathogen causing infection, not just that an infection exists. No guesswork in treatment.
Resistance Detection
Simultaneously identifies antibiotic resistance markers, enabling targeted therapy from day one.

Clinical Applications
PCR molecular testing is particularly valuable in these clinical scenarios:
Urinary Tract Infections
Rapid identification of UTI pathogens and resistance markers for targeted antibiotic therapy.
Respiratory Infections
Distinguish between viral and bacterial causes, identify specific pathogens quickly.
Wound Infections
Comprehensive pathogen detection in chronic and acute wound infections.
GI Infections
Rapid diagnosis of bacterial, viral, and parasitic gastrointestinal pathogens.
STI Screening
Highly sensitive detection of sexually transmitted infections.
Fungal Infections
Quick identification of dermatophytes and other fungal pathogens.
